UT3Tangent.is_orthogonal
========================

.. py:method:: t3toolbox.uniform_manifold.UT3Tangent.is_orthogonal(atol = 1e-09)

   .. code-block:: python

      def is_orthogonal(self, atol: float = 1e-9) -> NDArray:  # bool array, shape = frame stack C (scalar unstacked)


   True (per frame-stack element) if this tangent's frame is orthogonal. See
   :py:meth:`UT3Frame.is_orthogonal`. Reduce with ``.all()`` for a single verdict.
